Overview
The RAA489301ARGNP#HA0 is a switching controller IC manufactured by Renesas Electronics Corporation. It implements a 3-Level Buck or 2-Level Buck voltage regulator topology with pass-through mode capabilities. The device operates within an input voltage range of 4.5V to 24V and provides adjustable output voltages from 3V to 24V. It features a fixed switching frequency of 367 kHz and utilizes a 32-TQFN (4x4) surface-mount package.
Feature Summary
- Supports 3-Level Buck and 2-Level Buck topologies for enhanced efficiency
- Integrates pass-through mode functionality for direct power transfer
- Provides programmable output voltage control within specified limits
Applications
- Point-of-load voltage regulation in industrial systems
- Power management for battery-operated devices requiring efficient buck conversion
- Embedded systems utilizing 3-level buck converter architectures
Procurement Notes
Verify the specific suffix 'A3' against official documentation to confirm pinout and feature set, as suffixes often denote package variations or revisions. Ensure compatibility with your PCB footprint for the 32-TQFN package. Confirm RoHS3 compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.
Selection Notes
Select this component when a 3-level buck architecture is required to minimize ripple and improve efficiency compared to standard 2-level designs. The integrated pass-through mode makes it suitable for applications needing seamless transition between regulated and bypassed power states. Ensure the design supports the 367 kHz switching frequency constraints.
Part Context
This part belongs to the RAA489301 series of advanced power management ICs from Renesas. The series focuses on high-efficiency DC-DC conversion solutions using multi-level buck technologies. These controllers are designed to meet the demands of modern electronics requiring compact form factors and high power density.
Replacement Considerations
Consult the official datasheet for cross-reference information. Verify that any substitute component matches the 32-TQFN package dimensions and electrical characteristics, specifically the 4.5V-24V input range and 367 kHz frequency.
